Data Scientist, Integrity

OpenAI OpenAI · AI Frontier · San Francisco, CA · Data Science

Data Scientist role focused on building and scaling anti-fraud and abuse detection systems for OpenAI's platform, utilizing LLMs and large datasets to combat evolving threats.

What you'd actually do

  1. Design and build systems for fraud detection and remediation while balancing fraud loss, cost of implementation, and customer experience.
  2. Work closely with finance, security, product, research, and trust & safety operations to holistically combat fraudulent and abusive actors on our system.
  3. Stay abreast of the latest techniques and tools to stay several steps ahead of determined and well resourced adversaries.
  4. Utilize GPT-5 and future models to more effectively combat fraud and abuse.

Skills

Required

  • Python
  • SQL
  • experiment design (A/B tests, quasi-experiments, simulations)
  • quantitative analysis
  • large dataset exploration
  • fraud detection
  • abuse mitigation
  • communication skills
  • cross-functional influence

Nice to have

  • experience on a highly technical trust and safety team
  • experience with policy, content moderation, or security teams
  • deploying scaled detection solutions using large language models, embeddings, or fine tuning
  • experience as a data scientist at a hyper-growth company or research org

What the JD emphasized

  • anti fraud & abuse experience
  • new types of misuse
  • scaling our detection techniques and processes
  • most of the ways our technologies will be abused haven’t even been invented yet
  • highly technical trust and safety team
  • rigorous experiments
  • deploying scaled detection solutions using large language models, embeddings, or fine tuning
  • 5+ years of quantitative experience in ambiguous environments
  • fraud, abuse, or security problems
